Yea I was just going to say that too. Crumbling zakum gives you nice xp and a free helm. You get a quest for it at 50 and it even gives you free all cures and eye of fires. Alsooooo... I don't know if it's just me, but the helms that drop always give me class specific stats. Like 2% str for warrior, 2% for casters, 2% for dex users and so on. Not sure if this is just luck or working as intended.
